Question

If n(A) = 2, P(A) = 1/5 , then n(S) = ?
(A) 10
(B) 5/2
(C) 2/5
(D) 1/3

Answer 1

Solution :

Given n(A) = 2 , P(A) = 1/5,

n(S) = n(A)/P(A)

= 2/(1/5)

= 2 × 5

= 10

Therefore ,

n(S) = 10

Option (A) is correct.

Answer 2

Answer:

n(s)=10

Step-by-step explanation:

n(A)=2

p(A)=n(A) =1

n(S). 5

=2 =1

n(S). 5

=n(S)=10
